Wind, Solar, Biomass, Geothermal, Tidal n other alternative sources of energy, which do you think is the best?

There is no one solution. Our energy today comes from a mix of sources and it should always be that way. We need to develop as many clean and renewable sources as possible. Location will determine what is best to develop where.

I think not. A few years ago there was a lull over the UK for a week or so. 2006 I think, Xmas time. Turbines work within certain limits, too slow or too fast and they will not produce. There was little or no wind for a week. It was also very misty. So solar would have had an issue. Yesterday had much of the same conditions. I would like to see green energy a lot more but you will need backup for when the weather in the UK does not play by the rules of the proponents of wind and sun. Not really up on wave and tide power but there are days when the sea is quite calm and what happens at high and low tides? Genuine question there, I don't know.

Nuclear is the only alternative power source available today that can supply the massive amount of RELIABLE 24/7 energy we need at anywhere near a reasonable cost.

Solar and wind can be used as a supplement, but they are only good in certain areas and seasons, and only produce power about 35% of the time.

Depends where you live. Not all areas have good sun light. Not all areas have good wind. Not all areas are sitting on either an aquifer or hot spring.

The super negative is the price tag. For a 20 year investment at $30,000, these give you about 15 cents per kWh. Are you sure you want to lock in that rate for that long? Might be smart, might not be...

I agree with the others. I don't think any one of them is going to solve the problems. We can not put up enough windmills to produce enough power for everyone without having some other effect on the environment. A mix of several different types would be best. Solar in some areas works great but not in say Seattle. Wind works great in some areas but not well in say Boston. Water works great for areas that have water but not in a desert. I think making your power supply fit your local area is the best thought process.

Geothermal that heats a tidal source that creates steam on the solar turbines?

lol

I think if we used all of them, instead of "cheaper" options, we could turn our futures around.

wind and solar energy. Both are economical and less problematic from the point of envirment. We save national resources.

WIND and SOLAR

why?

WIND- first and foremost wind is free. Producing energy from wind will not produce byproducts, thus it is safe for the environment.

SOLAR- the earth has abundance of solar energy. It is FREE. It, too, does not have byproducts when we produce such, however, solar panels may be pricey.

why would you want to use only one? a combined usage is the most sensible. there isnt always wind or sun to use everyday so having multiple systems with your house/business would be better

a very very good example of a multisystem setup would be an earthship

I live in Florida (USA) - for us, solar power would be the best.

But we need to start using all of them as soon as possible.
